PU foamed wheels

A PU foamed wheel means a homogeneous polyurethane tire with air pores. It has similar properties as a pneumatic wheel, but it can not leak out air, and thus becomes maintenance-free. The attenuating feature of the pneumatic wheels is the same, but the rolling resistance is higher, so these wheels are best suited to lighter loads. At high static load for a longer period of time, the wheel may have a wheel plate. In unloaded mode, the wheel returns to its round shape after a certain amount of time.
